LOP Effect on Memory Types

LOP Effect on Memory Types Memory and its complexity involve systematic processes intent on successfully accessing and retrieving information (Atkinson, Shiffrin, 2016). The depth in which people process external information contributes to memory formation (Craik Lockhart, 1972). Moreover, the capacity for people to remember acquired knowledge depends on attention level, encoding level, and rehearsal level in which the information was processed (Craik Tulving, 1975). types of memory (implicit and explicit) along with the level-of-processing (LOP) involved in each. There is two types of memory implicit and explicit memory. Implicit memory can be described as habitually executing tasks that do not require intentional recall (Schacter, 1987). It has been suggested that implicit memory begins to develop in early infancy and remains constant in terms of improvement or deterioration through the progression of life (Và ¶hringer et al., 2017). Explicit memory can be described as intentionally executing tasks that require critical thinking and relies on the ability to recall (learned or experienced) information (Ullman, 2004). Explicit memory begins to develop after implicit memory and has a prolonged emergence (Richmond Nelson, 2007). Both types of memory are crucial and each serves a purpose (Sun, 2012). Adding depth to the type of memory is practical in terms of improving peoples memory. For shallow processing, stimuli are analyzed regarding sensory characteristics. On the other hand, deep processing is involved with the analysis regarding the meaning of the stimuli (Galli, 2014). Material processed while interpreting the meaning behind it is better for explicit memory than items processed using shallow operations at any level of depth. As a result, the characteristics of shallow and deep LOP are associated with the significance of the memory. The deeper the LOP, the easier the information could be recalled. The shallow LOP involves superficial aspects of stimuli and leads to the formation of a fragile memory. Conceptually-driven task and perceptually-driven task performance both depend on previously learned information pertaining to the stimuli in the task (Schwartz Yovel, 2016). Perceptual information can be described as physical aspects of the stimulus such as color while conceptual information can be described in terms of the stimulis purpose or meaning (Schwartz Yovel, 2016). Conceptual tests show implicit memory effect implying that only conceptually driven tests can affect the LOP. Perceptual reasoning only takes effect under explicit memory thus has no effect as far as LOP is concerned (Craik Tulving, 1975). In determining factors with LOP effect, studies show that only implicit triggers have an association with LOP thus concluding that only conceptually driven tests can show significant LOP effects. Major criticism on LOP and memory has been accounted by Craik (Craik Lockhart, 1972). Suggestions made that the conceptual framework of memory has advantages as it directs attention to the mental events and processes (Craik Lockhart, 1972). However, the issue of LOP has posed major difficulties, as retention ability is a function of depth and spread of processing (Craik Tulving, 1975). It offers no suitable criteria for indexing either depth or spread of the encoding. Craik also argues that encoding depth and spread appears to affect the retrieval ability to recall but are irrelevant in the determination of retrieval strategies. Both explicit and implicit memories have core functions in human functioning (Richmond Nelson, 2007). Different tests are carried out based on the two memories to determine their relationship with LOP. LOP should show strong effect with the explicit memory than implicit memory (Craik Lockhart, 1972). LOP is high for explicit memory as compared to implicit memory (Richmond Nelson, 2007). The hypothetical analysis aimed to determine the number of words remembered under the two models (Craik Lockhart, 1972). Deeper LOP should allow for remembrance of many words as opposed to shallow LOP. The purpose of the current experiment was to examine the LOP effect on the type of memory. It was hypothesized that deep LOP would result in the greater recall of words that were previously presented to participants during the deep LOP task compared to shallow LOP in both implicit and explicit memory. The main effect would occur and individuals in the deep LOP would remember more words in comparison to individuals in the shallow LOP and the outcome of LOP would be greater in the explicit memory task compared to implicit memory. It was further hypothesized that a dissociation between LOP and type of memory interaction effect would occur as deep LOP having a greater effect on the explicit condition. Method Participants Participants in the experiment consisted of 242 psychology students, 46 were male and 196 were female. The age in years amongst participants ranged from 19 years old to 60 years old (M = 25.22). Of the participants, 5.8% were Asian, 10.7% were African-American, 19.4% were Caucasian, 59.5% were Latino and 4.5% identified with other. All participants were english speakers, drafted within the San Bernardino area in California, and were considered a convenient sample. No incentives were given to participants. All participants were treated in accordance with the Ethical Principles of Psychologists and Code of Conduct (American Psychological Association, 2002). Materials A computer compatible with Microsoft powerpoint software and testing booklets was needed. The computer program included two types of orienting tasks (shallow and deep LOP). Each oriented task included 10 positive words and 10 negative words (see Appendix1). Shallow LOP task contained 20 words, 10 were positive, 10 were negative, half were presented in red and half were presented in green. The deep LOP task contained 20 words all presented in black. The experimental booklets included instructions for completing the test along with a consensus form for participants to mark giving consent to the experiment, a designated area containing several common traits used to identify or describe participants demographics in terms of gender, age and ethnicity. The experimental booklets included a distracter task of fill-in the blanks by beginning with the number 725 and counting backward by threes until all blanks were filled. The booklets designed to evaluate shallow LOP contained a word stem com pletion task. The word stem task contained partial words that were presented during the computer task. Participants were instructed to recall the words and complete the word stem. The booklets designed to measure deep LOP contained blank spaces and participants were instructed to fill in the blanks relying solely on the ability to recall the words presented to them on the computer task. The last piece of material provided participants with the debriefing statement and contact information for the corresponding coordinator. Procedure All participants were first invited to participate in the experiment. They were randomly assigned to one of four groups (DLEM, DLIM, SLEM, SLIM). Participants were placed in an environment without distractions while they carefully read the instructions. If they were in agreeance, participants were asked to mark the informed consent sheet and fill in the demographic information that best described them. Once participants were ready to begin, they initiated the start of the computer task. On the computer screen, participants were asked to respond to the given stimuli as fast as possible without the ability to regress and given two practice rounds. The participants in groups DLEM and DLIM were presented with deep LOP stimuli on the computer. While, participants in groups SLEM and SLIM, were given shallow LOP stimuli on the computer. Following the computer task, participants had to complete the distracter sheet. The final step to the packet was for either measuring implicit memory (parti cipants had a word stem completion task) or for measuring explicit memory (contained blank spaces for participants to fill in the blanks). Before participants departed they were handed a copy of the debriefing statement and simultaneously thanked for their participation in the study. Design A two-factorial design was implemented for the current study. The independent variable in the experiment was the LOP and qualifies as a categorical, qualitative variable with two levels (shallow and deep). The other independent variable of the experiment was the type of memory and qualifies as a categorical and qualitative variable that contained two levels (implicit memory and explicit memory). The dependent variable was the number of words correctly completed or correctly recalled meaning it was a quantitative variable. The main effect of the LOP on the total number of words completed or recalled correctly and the interaction effect between LOP and the type of memory on the total number of words completed or recalled correctly. A two-way analysis of variance (ANOVA) was used to examine significance (p t-test to further examine significance (p Results The purpose of the current study was to examine LOP and types of memory with the intention to measure the difference between deep LOP and shallow LOP. It was expected that participants in deep LOP would recall more words than participants in the shallow LOP. The study found that there was a significant main effect of LOP, F(1, 238) = 68.05, p = .000, this had a large effect size (Np2=.22).This means that deep LOP (M = 5.24) was better at word recall when compared to shallow LOP (M = 2.88). There was a significant interaction effect between LOP and type of memory, F(1, 238) = 12.51, p Np2 = .05). The effect of the deep LOP was greater on explicit tasks (M = 6.00) when compared to implicit tasks (M = 4.34). While shallow LOP had a greater effect on implicit tasks (M = 3.03) compared to explicit tasks (M = 2.73). Furthermore, two t-test showed that deep LOP was significantly better for explicit tasks, t(124) = 8.38, p t(114) = 3.32, p Figure 1). This means that participants in deep LOP remembered more words in comparison to participants in shallow LOP as expected. Discussion The purpose of the experiment was to establish whether different LOP would have an influence on types of memory. The LOP examined were shallow LOP and deep LOP along with the type of memory implicit and explicit memory. It was hypothesized that deep LOP would have a higher amount of recalled words compared to shallow LOP in terms of implicit memory and explicit memory. The results show the effect of deep LOP was greater on explicit tasks in comparison to implicit tasks this illustrations clear distinction with shallow LOP resulting with a greater effect on implicit tasks compared to explicit tasks. Additionally, it was further hypothesized that a dissociation would occur as an interaction effect between LOP and type of memory the results were as expected and the effect was greater at deep LOP and was reflected in the explicit condition. The current experiment expected that more words would be recalled at the deep LOP. The logic behind the hypothesis was that tasks involving deep LOP would require interpretation of the stimuli. As a result, in order to correctly interpret stimuli, individuals must concentrate on the task. Consequently, inciting deep LOP would force participants to pay more attention and would result in higher number of recalled words for the deep LOP task compared to the shallow LOP task. Deep LOP provides an opportunity to learn because it demands attention and if undivided attention is given to a task the deeper the LOP (Treisman, 1964). It was further hypothesized that a dissociative interaction effect would occur between LOP and type of memory with deep LOP having a greater effect on explicit memory. The logic behind the hypothesis is that dissociations are to be expected between conceptual and perceptual tasks (Weldon, Roediger, Beitel, Johnston, 1995). Moreover, unlike explicit memory, previous research has distinguished that aging has a small effect on implicit memory (Parkin, 1993). This means that it is possible for implicit memory to remain constant with permanency prevailing while explicit memory declines through the progression of age (Và ¶hringer et al., 2017). Such studies indicate that there are dissociative characteristics between processes and dissociative characteristics between the types of memory. The experimental results were expected. However, limitations of the experiment manifested in the form of intangible measures. Such measures include the difficulty of separating the depths of processes and systems. For instance, explicit memory also involves conceptual processes (Weldon et al., 1995). Future research must contribute to the formation of fixed stages of processing with corresponding thresholds. Doing so would mean a framework that theorizes on the overlapping of interaction between mental processes and types of memory. The current experiment could have implications in the mental health field. As mental disorders interact with types of memory much like amnesiac patients showing little impairment on implicit memory while demonstrating impairment on explicit memory (Warrington Weiskrantz, 1970). The experiment can aid in the interaction LOP could have on memory related mental disease. Such as a study involving diagnosed Alzheimers patients, which reported that Alzheimer patients showed little impairment in implicit test (Scott, Wright, Rai, Exton-Smith, Gardiner, 1991). Exercising procedures that incorporating implicit memory should help and improve mental state, however, because of the nature of the disease the benefits could be brief (Scott et al., 1991). In closing the current experiment has provided valuable information and insight into LOP and memory. The results indicate that deep LOP of explicit tasks could aid in memory improvement for explicit tasks and could be essential for critical thinking and strategic decision making when using this type of memory.

Princess Regional Trucking Company Essay

Princess Regional Trucking Company has been approached by a client with an opportunity that would require 120 trailers which is about 20 more than we currently own. We are not sure how long the relationship with this customer will last but this deal has the potential for considerable growth. I have a great deal of information for you regarding lease options that Princess Regional Trucking Company may want to consider before going forward with this deal. The first type of lease to consider is the direct financing lease. This lease is used by lessors in capital leases if the collections of minimum lease payments are guaranteed and the amounts of unrefundable costs are known in advance. In this type of lease the bank will buy new trucks and lease them to us instead of Princess Regional Trucking Company borrowing the money to purchase the trucks. The direct financing approach is the same as a loan. In order to arrange this type of lease we must show that the monthly payment will be met every month on time. This can be done by putting up assets to cover the payments just in case we cannot lease what is secured by the direct lease. Eliminating any question or doubt about the ability to cover the lease is the ultimate goal. If you would prefer to go with the Capital lease option then it must meet one of the four criteria according to FASB ASC 840-10-25-1. There has to be a transfer of ownership to the lessee by the end of the lease term, the lease contains a bargain purchase option, the lease term is equal to 75% or more of the estimated economic life of the leased property, or the present value at the beginning of the lease term of the minimum lease payments, equals or exceeds 90% of the excess of the fair value of the leased property. If any of the four criteria is met and also meets both of these criteria’s in that the lease payments have to be reasonable and the costs to be incurred are also predictable the lease is considered to be either direct financing or sales-type (http://highered.mcgraw-hill.com/sites/dl/free/0073526878/588542/Codification_Updates.pdf) The next type of lease to be addressed is a sales-type lease. Just like the capital lease there are for criteria that must be met. If the manufacture or dealer risks profit or loss then this would be a sales-type lease. This would mean that the seller would keep the assets in their inventory while the manufacturer or dealer are still earning profit or taking a loss. Under FASB ASC 840-30-35-22 the lessor must amortize the unearned income on a sales-type lease to income over the lease term to produce a constant periodic rate of return on the net investment in the lease.(http://highered.mcgraw-hill.com/sites/dl/free/0073526878/588542/Codification_Updates.pdf) Since the important part of a sales-type lease is the sale the initial direct costs of getting the lease is written off when the sale is recorded at the beginning of the lease. This would be noted on the income statement as a selling expense. The final type of lease option would be an operating lease. This type of lease allows use of an asset but does not transfer ownership of the asset. The assets are expected to be returned at the end of the lease agreement. This lease would give Princess the sole right to use the asset however the lessee would retain all risks and rewards of ownership. It would be shown as a rental expense on the balance sheet. It is considered an asset for us and gets depreciated like any other asset. This type of lease is usually short term but it can be cancelled if needed. Thank you for taking the time to review these three different types of leases for the additional trucks we need to satisfy our new customer. Since we are not certain the time frame of this relationship I would like to suggest going with the operating lease since it is more like a rental agreement.

Jamestown Essay - 666 Words

Jamestown nbsp;nbsp;nbsp;nbsp;nbsp;In the sixteenth century, England was one of the most powerful countries in the world. England was also in dire need of money at this time. In an effort to alleviate the country’s financial burdens, King Henry VIII decided to seize land owned by the Catholic Church. Henry then sold the already inhabited land to investors, and its residents were forced out. These people and their descendants would eventually become some of the fortune-seeking colonists that would settle America during England’s try at Imperialism. nbsp;nbsp;nbsp;nbsp;nbsp;In the early 1600’s England need money once again, and this time it decided to by settling the new land to the west of them.

This allowed disease to run rampant. Jamestown only lasted until 1700 when its settlers abandoned it, and moved Williamsburg. The colonist’s primary objective, as mentioned before, was to make money, and also try and drive out Spanish colonies. None of the colonists concentrated on survival and focused on their search for prosperity. Because of all the time spent on looking for gold or the route to China, and their lack of skills, the colonists were not prepared for the harsh upcoming winter. The results were devastating. During the winter of 1609 – 1610 almost ninety percent of the colony was wiped out, and only 50 out of the 500 colonists survived. nbsp;nbsp;nbsp;nbsp;nbsp;The government of the colony consisted of a governor and 12 council members, all whom were appointed. The government, named the Virginia Council, had no decision making power at all. Everything was sent over to England, settled there, and then sent back. This system was outrageously inefficient and often took several years for anything to be resolved. This absurd and inept council was another reason the death toll at the colony was so high.
